A SaaS company utilizes AWS PrivateLink to host a service, which runs on three EC2 instances behind an NLB in private subnets across multiple AZs in the eu-west-2 region. All existing customers are located in eu-west-2. The company has acquired a new customer in the us-east-1 region and has set up a new VPC with subnets in us-east-1, establishing inter-Region VPC peering between the two regions. The company aims to provide the new customer with access to the SaaS service without immediately deploying new EC2 resources in us-east-1. Which solution meets these requirements?
A
Configure a PrivateLink endpoint service in us-east-1 to use the existing NLB in eu-west-2 and grant specific AWS accounts access to the SaaS service.
B
Create an NLB in us-east-1, establish an IP target group using the eu-west-2 instances' IP addresses, configure a PrivateLink endpoint service with the us-east-1 NLB, and grant specific AWS accounts access to the SaaS service.
C
Deploy an ALB in front of the eu-west-2 EC2 instances, create an NLB in us-east-1, associate the us-east-1 NLB with an ALB target group using the eu-west-2 ALB, configure a PrivateLink endpoint service with the us-east-1 NLB, and grant specific AWS accounts access to the SaaS service.
D
Utilize AWS RAM to share the eu-west-2 EC2 instances, create an NLB and an instance target group in us-east-1 including the shared instances, configure a PrivateLink endpoint service with the us-east-1 NLB, and grant specific AWS accounts access to the SaaS service.
